Most of the time one already knows at the call site if it's a Field,
a Procedure etc --- so use that instead.
For now I'll leave the corresponding getters that are basically
documented as "don't use" ("[...] for convenience, not efficiency.
Consider manually iterating the members [...]").

During constant evaluation, unused arguments to a const constructor are
thrown away after evaluation, since their values do not affect the
resulting instance constant. If such an unused argument ends up
unevaluated, any errors that would arise in the final evaluation are
not reported.
This CL adds space in the Kernel AST for saving these unevaluated
expressions so they can be checked during final constant evaluation.
Even though this is an incompatible change, no update is needed to the
VM code (except for the version bump), since the VM does not support
InstanceCreation nodes in the first place.

If there are circular references between type parameters and types in the bounds,
currently serialization leaves original type parameters unchanged, which results
in failures to serialize compiled expression procedure.
This CL makes sure to clone all type parameters first, then passes map

Previously, if we didn't include the source code, we wrote the url as
null. This for instance made it impossible to step through mixed in code
(at least when mixed in from the sdk).
This CL includes all used urls. If there's no source, the source is empty,
but the VM then tries to find the proper source to be able to display it
(e.g. the VM already has the sdk source).
This CL further more adds a service test that tests that we can actually
step into mixin in code from the sdk.

Prior to this change we only had fileOffset which points to the name.
This CL adds a field - startFileOffset - that points to the start
(e.g. 'static', 'factory', the return type or any presiding annotation
(including '@')), as well as fixing `Function::GetSource` in the VM to
fix a crash when using mirrors to ask for the source of a function or
constructor.
The field is added to procedures, constructors and classes.
The latter changes the location of classes with annotations to be
the position of the annotation. This is on-par with --no-preview-dart-2.
The change in regards to procedures and constructors mean, that both
the location and the source (from .location and .source on a
MethodMirror) will change to include any annotations. This is a
different behavior than --no-preview-dart-2.
Closes#33271.

Translate assert statements in async functions. The translation of
the condition subexpression can produce a sequence of statements that
have been hoisted out of it. These need to be guarded so they are
executed only when asserts are enabled.
For this purpose, we introduce an AssertBlock. The semantics of the
assert block:
assert { s0; ...; sn; }
is the same as:
if (assertsEnabled) { s0; ...; sn; }
where assertsEnabled is a more primitive nullary expression that is
true iff. assertions are enabled. We chose not to encode this using a
construct like assertsEnabled because (1) we would have to support it
appearing as an arbitrary expression which we don't currently need
and (2) it requires deeper pattern matching to detect and skip the
guarded code when desired.
The translation is more complicated because if there is a message
subexpression in an assert, it is conditionally evaluated only if the
assert's condition is false.

This CL changes:
* package:kernel/clone.dart: To not clone file offsets if the
file-uri we copy from is unknown.
* package:kernel/binary/ast_to_binary.dart: To not write out file
offsets if the file-uri is not written/indexed (which happens if
the file uri is not in the `Program.uriToSource` map).
* It reverts the file renaming part of 60a2cfa219 which
fixed the name collision problem only partially (it missed to
rename `runtime/lib/double.dart`, which is not possible because
there's already a `double_patch.dart` file).
Instead of renaming, we solve the problem by mangling the names as follows:
.../sdk/lib/core/double.dart -> dart:core/double.dart
.../runtime/lib/double.dart -> dart:core/runtime/lib/double.dart
.../runtime/lib/double_patch.dart -> dart:core/runtime/lib/double_patch.dart
* It changes the test to ignore any negative token positions. The vm
service does not just expose `-1` token positions for places where
there is no source, but also e.g. `-9` (which means TokenPosition::kMethodExtractor),
this was one reason why the appjit test failed.
* It changes the test to try to force-compile everything (unsure if that works).

This CL also adds a service/valid_source_locations_test, which loops
over libraries/classes/fields/functions and obtains source locations for
them, including line numbers. This ensures that if there is a source
location attached to a member, we can use it's token position to get to
the line number.
This CL also changes package:kernel's [Cloner] to clone fileOffsets (and
not just fileEndOffsets). This is important for mixin resolution, where
we copy members into mixin application classes.
